[Core] Add Raspberry Pi RP2040 support (#14877 )

* Disable RESET keycode because of naming conflicts * Add Pico SDK as submodule * Add RP2040 build support to QMK * Adjust USB endpoint structs for RP2040 * Add RP2040 bootloader and double-tap reset routine * Add generic and pro micro RP2040 boards * Add RP2040 onekey keyboard * Add WS2812 PIO DMA enabled driver and documentation Supports regular and open-drain output configuration. RP2040 GPIOs are sadly not 5V tolerant, so this is a bit use-less or needs extra hardware or you take the risk to fry your hardware. * Adjust SIO Driver for RP2040 * Adjust I2C Driver for RP2040 * Adjust SPI Driver for RP2040 * Add PIO serial driver and documentation * Add general RP2040 documentation * Apply suggestions from code review Co-authored-by: Nick Brassel <nick@tzarc.org> Co-authored-by: Nick Brassel <nick@tzarc.org>

 `EEPROM_DRIVER = vendor` (default) | Uses the on-chip driver provided by the chip manufacturer. For AVR, this is provided by avr-libc. This is supported on ARM for a subset of chips -- STM32F3xx, STM32F1xx, and STM32F072xB will be emulated by writing to flash. STM32L0xx and STM32L1xx will use the onboard dedicated true EEPROM. Other chips will generally act as "transient" below.
 `EEPROM_DRIVER = i2c`              | Supports writing to I2C-based 24xx EEPROM chips. See the driver section below.
 `EEPROM_DRIVER = spi`              | Supports writing to SPI-based 25xx EEPROM chips. See the driver section below.
 `EEPROM_DRIVER = transient`        | Fake EEPROM driver -- supports reading/writing to RAM, and will be discarded when power is lost.
+`EEPROM_DRIVER = wear_leveling`    | Frontend driver for the wear_leveling system, allowing for EEPROM emulation on top of flash -- both in-MCU and external SPI NOR flash.

+## Wear-leveling Driver Configuration :id=wear_leveling-eeprom-driver-configuration
+
+The wear-leveling driver uses an algorithm to minimise the number of erase cycles on the underlying MCU flash memory.
+
+There is no specific configuration for this driver, but the wear-leveling system used by this driver may need configuration. See the [wear-leveling configuration](#wear_leveling-configuration) section for more information.
+
+# Wear-leveling Configuration :id=wear_leveling-configuration

+`WEAR_LEVELING_DRIVER = legacy`         | This driver is the "legacy" emulated EEPROM provided in historical revisions of QMK. Currently used for STM32F0xx and STM32F4x1, but slated for deprecation and removal once `embedded_flash` support for those MCU families is complete.
+
+!> All wear-leveling drivers require an amount of RAM equivalent to the selected logical EEPROM size. Increasing the size to 32kB of EEPROM requires 32kB of RAM, which a significant number of MCUs simply do not have.
+
+## Wear-leveling Embedded Flash Driver Configuration :id=wear_leveling-efl-driver-configuration
+
+This driver performs writes to the embedded flash storage embedded in the MCU. In most circumstances, the last few of sectors of flash are used in order to minimise the likelihood of collision with program code.

+`#define WEAR_LEVELING_EFL_FLASH_SIZE`   | _unset_     | Allows overriding the flash size available for use for wear-leveling. Under normal circumstances this is automatically calculated and should not need to be overridden. Specifying a size larger than the amount actually available in flash will usually prevent the MCU from booting.
+`#define WEAR_LEVELING_LOGICAL_SIZE`     | `1024`      | Number of bytes "exposed" to the rest of QMK and denotes the size of the usable EEPROM.
+`#define WEAR_LEVELING_BACKING_SIZE`     | `2048`      | Number of bytes used by the wear-leveling algorithm for its underlying storage, and needs to be a multiple of the logical size.

+## Wear-leveling SPI Flash Driver Configuration :id=wear_leveling-flash_spi-driver-configuration
+
+This driver performs writes to an external SPI NOR Flash peripheral. It also requires a working configuration for the SPI NOR Flash peripheral -- see the [flash driver](flash_driver.md) documentation for more information.
+
+Configurable options in your keyboard's `config.h`:
+
+`config.h` override                                 | Default                        | Description
+----------------------------------------------------|--------------------------------|--------------------------------------------------------------------------------------------------------------------------------
+`#define WEAR_LEVELING_EXTERNAL_FLASH_BLOCK_COUNT`  | `1`                            | Number of blocks in the external flash used by the wear-leveling algorithm.
+`#define WEAR_LEVELING_EXTERNAL_FLASH_BLOCK_OFFSET` | `0`                            | The index first block in the external flash used by the wear-leveling algorithm.
+`#define WEAR_LEVELING_LOGICAL_SIZE`                | `((block_count*block_size)/2)` | Number of bytes "exposed" to the rest of QMK and denotes the size of the usable EEPROM. Result must be <= 64kB.
+`#define WEAR_LEVELING_BACKING_SIZE`                | `(block_count*block_size)`     | Number of bytes used by the wear-leveling algorithm for its underlying storage, and needs to be a multiple of the logical size.
+`#define BACKING_STORE_WRITE_SIZE`                  | `8`                            | The write width used whenever a write is performed on the external flash peripheral.
+
+!> There is currently a limit of 64kB for the EEPROM subsystem within QMK, so using a larger flash is not going to be beneficial as the logical size cannot be increased beyond 65536. The backing size may be increased to a larger value, but erase timing may suffer as a result.
+
+## Wear-leveling Legacy EEPROM Emulation Driver Configuration :id=wear_leveling-legacy-driver-configuration
+
+This driver performs writes to the embedded flash storage embedded in the MCU much like the normal Embedded Flash Driver, and is only for use with STM32F0xx and STM32F4x1 devices. This flash implementation is still currently provided as the EFL driver is currently non-functional for the previously mentioned families.
+
+By default, `1024` bytes of emulated EEPROM is provided:
+
+MCU       | EEPROM Provided | Flash Used
+----------|-----------------|--------------
+STM32F042 | `1024` bytes    | `2048` bytes
+STM32F070 | `1024` bytes    | `2048` bytes
+STM32F072 | `1024` bytes    | `2048` bytes
+STM32F401 | `1024` bytes    | `16384` bytes
+STM32F411 | `1024` bytes    | `16384` bytes
+
+Under normal circumstances configuration of this driver requires intimate knowledge of the MCU's flash structure -- reconfiguration is at your own risk and will require referring to the code.

 Tips:

 * The smoothness of the cursor movement depends on the `MOUSEKEY_INTERVAL` setting. The shorter the interval is set the smoother the movement will be.  Setting the value too low makes the cursor unresponsive.  Lower settings are possible if the micro processor is fast enough. For example: At an interval of `8` milliseconds, `125` movements per second will be initiated.  With a base speed of `1000` each movement will move the cursor by `8` pixels.
-* Mouse wheel movements are implemented differently from cursor movements. While it's okay for the cursor to move multiple pixels at once for the mouse wheel this would lead to jerky movements. Instead, the mouse wheel operates at step size `1`. Setting mouse wheel speed is done by adjusting the number of wheel movements per second.
